This work presents a detailed investigation of the effect auxeticity synergised with pyro-coupling behaviour multiphase magneto-electro-elastic (M-MEE) composites using finite element (FE) framework. The nonlinear deflection and bending problems sandwich plates auxetic core M-MEE skins subjected to multi-physics load (electric, magnetic thermal) are probed. plate kinematics is governed by Reddy...

Spin-valves had empowered the giant magnetoresistance (GMR) devices to have memory. The insertion of thin antiferromagnetic (AFM) films allowed two stable magnetic field-induced switchable resistance states persisting in remanence. In this letter, we show that, without the deliberate introduction of such an AFM layer, this functionality is transferred to multiferroic tunnel junctions (MFTJ) all...

In this study, we first demonstrate that the J-integral in classical linear elasticity becomes path-dependent when the solid is subjected to combined electrical, chemical and mechanical loadings. We then construct an electro-chemo-mechanical J-integral that is path-independent under such combined multiple driving forces. Further, we show that this electro-chemo-mechanical J-integral represents ...

This work presents the background and derivation of Cramér-Rao bounds on the errors of estimating the parameters (moment and location) of a dynamic current dipole source using data from electro- and magneto-encephalography. A realistic head model, based on knowledge of surfaces separating tissues of different conductivities, is used.

Abstract In this present study, the nonlinear thermal-magneto-mechanical stability and vibration of branched nanotube conveying nano-magnetic fluid embedded in linear elastic foundations are analyzed. The governing equations established via Euler–Bernoulli theory, Hamilton’s principle, nonlocal theory elasticity. flow thermal behaviors nanofluid described using modified Navier–Stokes conservati...

This work reports on a novel magnetorheological polymer gel with carbon nanotubes and carbonyl iron particles mixed into the physical cross-linked matrix. The resulting composites show unusual nonlinear magneto-electro-mechanical responses. Because of low matrix viscosity, effective conductive paths formed by CNTs were mobile high-performance sensing characteristics observed. In particular, due...

The nonlinear two-degree-of-freedom system under consideration consists of the linear oscillator with a relatively big mass, which is an approximation of some continuous elastic system, and of the vibro-impact oscillator with a relatively small mass, which is an absorber of the linear system vibrations. Analysis of nonlinear normal vibration modes shows that a stable localized vibration mode, w...

The magnetic circular dichroism and the Faraday rotation are the fundamental phenomena of great practical importance arising from the breaking of the time reversal symmetry by a magnetic field. In most materials, the strength and the sign of these effects can be only controlled by the field value and its orientation. Furthermore, the terahertz range is lacking materials having the ability to af...
